Founder — Poison Pill permanent-closure retrospective ↗ · Checked 25 Oct 2026

Verification notes

Shutdown: The maker’s current project page explicitly says he shut Poison Pill down in2026; his dated April14 retrospective identifies that complete product separately from Aux and explains the end. Display April14 as an inferred permanent-closure announcement/retrospective proxy, not the actual technical end day or first customer notification. This was a complete named upload-to-protected-download application with its own dashboard and billing, not a research model/API catalogue. TensorFlow/model-adversarial processing was the core task. The developer explicitly reports poor cross-model generalization and a licensed-training-data barrier; no guaranteed protection or proven inaudibility is endorsed. The project-page November5,2025 date and Devpost project timestamp are not assumed to establish first public availability. Other maker products continue. Exact cutoff, hour and time zone remain unknown. Closure source
